So far I have put 100's of hours on my WA 22, and most of the recent ones using the 596 in combination with 5998 power tubes & a variety of driver tubes without blowing a single fuse... haven't had a look at the top pins recently, but remember they were pretty dull & dark looking when I first installed the adapter (Woo's)

Hope you can figure it out, let us know how it goes! P.S.: I had some trouble to get the top plugs to seat correctly on the top pins (secure fit without pushing too hard to get them in...) so that's one thing I'd check (don't know enough about electronics if that kind of loose connection may cause the fuse to blow)

ive never had a problem with fuses on any of my tubes, 596, 274b, gz34, or any other.

you might have a bad tube or maybe an issue with the amp, i'd send jack an email about it.

Thanks for the tip guys, do you happen to know what amp rating are your fuses? I'm about to head to ratshack to get a 3amp one to see if that helps.

That is definitely sounding like a bad tube. I'd be careful running it until you can confirm otherwise as it may be heading toward a more spectacular failure.

Do you have access to a tube tester?

I'm wondering if maybe I should be using a 3 amp fuse (the Woo Audio manual says 2 or 3 amps are both usable). If anyone with a 596 can pull out their fuse to check what amp rating yours is would be appreciated.

The fuse blows within 5 second of power up when using the 596 and it seems like my 596 top pins are darker then I remember them being so I'm wondering if i got a bad tube....

what do you guys think?

I sent Jack an email I hope he gets back to me.

WooAudio WA 6 Special Edition + USAF-596 (The Mighty 596) + Furutech 3A fuse? Never! J-Wu will get back to you, no doubt. Hope you get it sorted.

Be careful about putting a larger amp fuse in your amp. You're allowing the amp to draw more current than it's designed to-- before the fuse blows. You can do damage to the other components inside the amp which aren't rated for the higher capacity.

I went back to 2 amp. The only reason I thought to try a 3 amp was because the owner's manual says 2 amp or 3 amp was acceptable.
